tube amp and spotify

Regardless of tube or SS BMC PURE DAC
great sound versatile and value

For myself, I was thinking about getting the Parasound. It has a volume control and doesn't need any drivers, so it can be used with Win, Mac or Linux. For internet streaming, it should work very well.

Find a Wadia 121 if you can. It's musical and detailed, and with digital that's a tough balancing act.

I have the Parasound zDac and am very pleased. It is actually way better than the poor quality Spotify Premium signal.

You really should consider ditching Spotify for Tidal. There is no comparison sound quality wise. Tidal's catalog is smaller but still pretty vast, it's well worth the $20 a month they charge.
